How to change partition size in Windows Server 2016?

All disk partitions are created when building the server, but the disk partitions may not meet your needs after running this server for a long time. The typical disk space issue is C drive getting full, so there is not enough free space to keep server running smoothly. With partition software you can change partition size of the existing drives without starting from scratch. Besides shrink and extend partition, you can spit, merge, copy disk volumes and much more. Today I’ll show you how to change partition size in Windows Server 2016 without losing data.

1. Change partition size by reallocating space

Step 1:Download and install Partition Assistant Server, right click the drive that has plenty of free space and select “Allocate Free Space“.
